Loading device used for rigidity test and capable of realizing contact indication and use method of loading device

Abstract

A loading device for a rigid test of contact indication, comprising a frame (5), a loading trolley (9) capable of moving left and right on the frame (5), and a loading trolley (9) fixed at the left end of the frame (5) for The clamping table (11) for clamping the workpiece (1), wherein, the right side of the loading trolley (9) is fixedly connected with an externally threaded sleeve (7) for extending into the hollow interior of the rotating shaft (6) and The inner threaded ring portion (71) at the left end of the rotating shaft (6) is threadedly fitted, and the right end of the rotating shaft (6) is fitted with the drive on the right side of the boss (51) of the frame (5). The output shaft of the motor (8) is power-connected, and two roller assemblies (91) are installed on the lower side of the loading trolley (9) from left to right, and each of the roller assemblies (91) includes a one-way bearing And for the rollers engaged with the frame (5).

Description

technical field [0001] The invention relates to the field of material testing equipment, in particular to a loading device for contact indication rigidity testing and a method for using the same. Background technique [0002] The rigidity test of the material is an important index for the material performance of the workpiece. Materials may deform differently under different loads and thus exhibit different stiffness properties. Some existing testing equipment continuously applies gradually increasing loads to materials and measures the amount of deformation that occurs during the process. Due to the dynamic nature of load changes and the immediacy of measurement, this method is prone to cause measurement errors. For equipment with fixed value applied load, due to the discreteness of fixed value, it is difficult to obtain the point performance of expected value at any time. Moreover, slight fluctuations in the load are prone to occur during the hold of a fixed value, resu...

Problems solved by technology

Due to the dynamic nature of load changes and the immediacy of measurement, this method is prone to measurement errors

For equipment with fixed value applied load, due to the discreteness of fixed value, it is difficult to obtain the point performance of expected value at any time

Moreover, slight fluctuations in the load are prone to occur during the hold of a fixed value, resulting in measurement errors

And although some equipment can guarantee the measurement accuracy, the cost is high and the maintenance work is complicated
